Buckwheat husks are the shells that protect the buckwheat kernel from various elements of nature. These husks are cleaned with air and sifted to remove debris and dust so they can be used as pillow fill. The slightly curved shape of the husk segments tend to interlock together when used in the thousands as a pillow fill, enabling them to hold their shape without collapsing or bouncing back like other fills such as polyfill, foam, or feathers do.

Despite what it’s name suggests, buckwheat is actually a fruit related to rhubarb, not a type of wheat, cereal or grass. Grown inside the husk, buckwheat kernel or groats is a highly nutritious food, the dried fruit is eaten whole or ground into flour.
